HEELrCLAMPING DEVICE.

T 0' all whom it may concern:

Be it known thZLh-L'JOHN P. HUBER, :1 citizen of the United States, residing in the city of St. Louisand Stateof Missouri, have invented certain new and useful Improvements in Heel-Clamping Devices, of which the following is a specification. I V

. My invention relates to improvements in heel-clamping devices and has for anobject to provide such a devicev which may be quickly and conveniently operated to clamp a heel to a shoe for holdingv said heel in position thereon until an adhesive applied to the heel has set sufiiciently to hold the heel in position upon the body of said shoe. A further object of the invention is to provide an element in the form of a removableheel-engaging block adapted'to be positioned upon a heel and act as a pressuredistributing element ,when pressure. is

brought to bear upon it. 7

Other. objects and advantages will appear in the following specification. and the novel features of the invention will be particularly pointed out in the claims hereto appended.

- I attain these objects by the combinations, constructions and arrangements of parts illustrated, as to a particular embodiment of the. invention, in the accompanying drawings forming .a part of this specification.

Referring to the drawings: Fig. 1, is a rear elevation of a heel clamp device constructed in'accordance withmy invention. j Fig. .2, is an end elevation thereof.

-Fig. 3, is a detail-full size, showing a .wood

heel clampedto a shoe;

Fig. 4,,is a detail showing a portion of a shoe,a last and its'suppor In carrying out my invention, I employ a suitable bench like table, illustrated in the drawings asconsisting of a suitable narrow tabletop 1 supported by means of suitable legs. 2. .The; deviceis :preferably provided upon its front adj acent. the. top 1 with a suitable; work receiving and supporting shelf 3. The supporting table may be suitably. bracedas at 4 or in any similarmanner "to. lend rigidity V and strength to the structure. Y

the top member lin suitable spaced relation and are suitably held in fixed relation tothe top 1;

A cross-piece 6 is supported by the upper An interiorly threaded screw-shaft supporting member 11 is fixed to the under surface of the cross-piece. 6 in alignment with each last-supporting standard 9, as clearly shown in Figure ,1.

A suitably threaded set-screw or screwmember 12 having. its lower end provided with a swivel-head 13 is operatively supported or carried by each interiorly threaded screw supporting member 11. The upper end of each screw member 12 is adapted to be suitably shaped to receivea removable hand-wheel l l -adapted to be manually operatedforimparting a rotary up or down movement to'the. screw-members 12. f

. One of the features of my present invention is the employment ofran improved heel engaging pressure distributing member of a removable-unittype, and so designed as to engage both theatreadface and a portion of the rear face of a heel being glued to a simultaneously to both the tread and rear face; of the 'heel when pressure is-applied to the member.

Each block consists of a 1 5 hav shoe to, distribute perpendicular pressure ing a flat upper pressure receiving surface 16, and a. heel engaging surface. 17 adapted to engage [the tread face-of heels such as 18.

j Each block 15 is provided with an additional surface 20 which isprefe'rably covered with" a suitable pad 21, such as felt or its equivalent. This pad 21 is adapted to engagethe. back face of the heel 18, as clearly 7 shown in Figurev 3, a-nd prevents the'rear surface of the heel from being scratched or defaced. The shape of the face 20 may be variedto fit any form of heel, It is es sential though, that the block 15 should be of such shape so as to engage two surfaces of a heel, namely, the tread surface and the rear surface. g 4 \Vhen a shoe positioned upona last 22 is mounted upon any one of the last-supporting standards 9, the next step or operation is to position a heel 18 having glue or other.

adhesive applied to its heel seat end, upon the body of the shoe, as shown 111 Figure 3. The next step is then to position a heel engaging, pressure-distril: uting block 15 upon the heel l8 and turn the screw member 12 in a direction to cause the screw to move downwardly, thereby bringing the swivel-head 13 thereof into engagementwitl'i the flat top surface 16. This operation will apply the desired pressure to the block 15, which will, in turn, distribute the pressure exerted thereupon evenly upon the heel l8.

The improved means herein described firmly and evenly holds the heel in its proper position upon the shoe body until theglue has thoroughly set. Then the swivel-head 13 is raised by turning the screw in the opposite direction so that the block 15 may be removed from engagement with the heel and the shoe and last removed from the support.

It has been found that by the use of this improved heel-clamping device a shoe may,

after the heel has been glued thereto, be passed along and worked upon without first havingto remove the last and nail the heel to the shoe from the inside, as is now cus- 'tomary. This'is a great advantage, as it I glue had set, as they would not stand the strains applied in handling unless theheels were also nailed to the shoe. This necessitated the removal of the last from the shoe before the operationswere completed. This is not the case with heels which are glued to shoes and clamped into position by means of the device herein described. This is due tov 'the fact that thepressu're is properly distributed through the medium of the block 15. The many advantages of the hereihdescribed invention will readilysuggest thems lves to those skilled in the art to whichit a pertains.

I am aware that changes may be made in the construction and arrangements of the several parts of the herein described device, which will still be within the scope of my invention. Hence I reserve the right to make, any such changes as may be covered by the appended claims,

What I claim is:

1. A heel clamping device comprising in combination, a standard adapted to support a shoe having a gummed heel seatingsurface, a verticallydisposed pressure-exerting member movable toward and from the heel portion of the shoe, and a heel-pressure distributing member of such shape and size as to engage boththetread "surface and rear surface or 'a heel having a gummed seat adapted for seating engagement with the.

gumm'ed heelfseating surface of theishoe,

said vertically 1 disposed pressure-exerting member adapted tobe forced into engagementwith the top surface of the heel-pressure-distributing member at such a point along its length as to exert, and equally dis-Y tribute perpendicular pressure through the heel-pressure-distributing member simulta neously upon both the tread surface and rear surface of the heel when positioned upon the shoe for tightly and uniformlypressing the gummed seat of the heel upon the gummed heel seating surface of the shoe and retaining the heel in, a non-slipping p0- sitionu'pon the shoe while applying pressure'to the heel'without initially nailing the heel to the shoe.

2. A heel clamping .device comprising in combination. a standard adapted to support a shoe to which a heel is to be secured, a

screw-threaded clamping member movable toward and from the standard, and a heel pressure-distributing Inemberhaving a heelengaging surface arranged simultaneously to engage both'the tread face'and rear face of a shoe heel and to prevent'forward and rearward movement of the heel while pressure 'is being exerted'upon the heel-pressuredistributing member. said member being further provided with a hat upper clampen a incr face dis nosed in a substantiall Z? .2

horizontal plane when the pressi'ire-distributing member is positioned upon thetread surface of the heel to be glued to the shoe and into contact with which face the clainp- 7 ing inembermay move uponthe rotation of v its screw.

A heel clampingfdeviee comprising in combination, a 'standard adapted to support a shoe to which a heel is to be secured, a clamping member movable toward and from the standard, and a heel-pressure-distributing member having heel-engaging surfaces arranged to meet at the edge of th'e tread surface and diverging therefrom si n'iul ta i neously to contactwi'th the treadface and ram faceofthe heel to prevent displacement of theheel upon the shoe when applying pressure to the pressure-distributing member.

4. A heel-pressure-distributing member having a depression furnishing two heelengaging surfaces, one of said surfaces adapted to engage the tread surface of a heel and to prevent the heel from slipping forward upon the shoe while the pressure distributing member is under pressure to distribute perpendicular pressure throughout the forward portion of the heel, and the other of said surfaces adapted simultaneously to engage the adjacent portion of the rear face of the heel, to prevent the heel from slipping rearwardly upon the shoe and simultaneously to distribute perpendicular pressure throughout the rearward portion of the heel.

5. A heel-pressure-distributing member comprising an integral body having a flat upper clamp-engaging surface, an opposite inclined surface adapted to engage the tread surface ofa heel and a curved surface diverging from the inclined surface and adapt ed simultaneously to engage a portion of the rear face of the heel, both of said heel-en gaging surfaces being adapted simulta plied to the pressu-re-distributiing member, and to provide means for simultaneous engagement with the rear surface of the heel the pressure distributing member to prevent displacement of the heel being gummed I to the shoe while under pressure.

7. A heel-pressuredistributing member having a main body portion provided with a plane clamp-engaging upper face, said body portion having a plane lower face inclined relatively to the plane of the upper face and adapted to engage the tread surface of the heel of a shoe, and said main body portion being provided with a pendent body portion having a surface meeting the tread-engaging surface and adapted for simultaneous engagement with the rear face of the heel so that pressure on the upper face will be transmitted to the heel in a direction normal to the heel seat.

8. A heel-pressuregdistributing member comprising a block having a fiat upper clamp-engaging surface, there being a depression in the block furnishing a surface in a plane inclined to the plane of the upper surface and adapted to engage the tread surface of the heel and an adjacent surface adapted to engage'the rear face of the heel so that pressure'on the upper surface will be transmitted to the heel while slipping thereof is positively prevented.

In testimony whereof, I have hereunto signed my name to the specification.

JOHN P. HUBER.
